The semi-comprehensive list I assembled yesterday of people largely affected by this was:
* women
* transgender folk
* gay/lesbian/bisexual folk
* people whose names ID them as belonging to an ethnic minority
* people with unusual names
* famous people & celebrities
* people who work in law enforcement
* soldiers & military officers
* government employees
* people in the witness protection program
* professionals
* academics
* registered sex offenders
* minors (though I think minors aren't allowed to have an account in their name)
